Frequently asked questions

What is the stiff NAS rear mudflap?
This is the left-hand rear mudflap in the stiff NAS pattern, a rigid moulded flap rather than the flexible rubber type. It mounts behind the rear wheel and shields the rear body panels, the crossmember and following traffic from stones, mud and spray. Supplied as an assembly for one side.
What's the difference between the stiff NAS flap and the rubber type?
The stiff NAS flap is a rigid moulded design, where the standard flap is flexible rubber. The rigid pattern holds its shape better but is less forgiving on impact, so match it to the mounting your vehicle already uses.
Which Defender does the LH rear flap fit?
It fits the Land Rover Defender 90, 90-inch wheelbase only, Hard Top and Soft Top, left-hand rear. Fitment runs to VIN FA414686. Check your VIN and side before ordering.
